Hi All, I'm trying to programatically (using c#) read the file properties (Title,
Summary, Author, Comments etc.... The stuff that shows up on the Summary tab
when you see the properties of a file). FileInfo and FileSystemInfo classes expose only the standard properties
(create time, mod time etc..). Any pointers would be greatly appreciated.

See the following newsgroup post from 2/28/2000. The Summary tab is a
proprietary shell extension, it gets part of its info from direct knowledge
of some file types, and other info from plugins, but the plugin COM
interfaces were never published. Looks like there was some interest in
reverse-engineering them over the years, but it doesn't appear that anyone
ever did.
